A conveying member, especially a rotor or stator, for conveying a flowable, preferably gaseous medium, comprises a plurality of blades (S-S) arranged following each other with a circumferential distance in a circumferential direction (U) around a central axis (A). Either a first circumferential distance (a) or a second circumferential distance (b) differing from the first circumferential distance (a) is provided between a blade and a respective blade following it in the circumferential direction (U) in a group of blades directly following each other in a circumferential direction (U), which the group comprises at least some of the blades (S-S). The first circumferential distance (a) is provided between at least two blades (S-S) located directly adjacent to one another, and the second circumferential distance is provided between at least two blades (S-S) located directly adjacent to one another.

Conveying member, especially rotor or stator, for conveying a flowable, preferably gaseous medium

An exhaust muffler for a fuel-operated heating device has upper and lower housing half shells, an exhaust gas through-duct and absorption and reflection chambers. The exhaust muffler is connectable to an exhaust pipe of the heating device. The exhaust gas through-duct has an inlet pipe of a single absorption chamber and a single following reflection chamber that are separated by a partially perforated partition, with double reversal of the exhaust gas flow, and an outlet pipe; the inlet pipe being perforated on the outer surface side, with an S-shaped curved section and a straight end section, and the outlet pipe being a straight outlet pipe, closed on the outer surface side, and the straight section of the inlet pipe runs parallel to, and at a spacing from, an inlet section of the outlet pipe.
